Spider Identification Guide: A pictorial guide to the conspicuous spiders of Orange County, California

Leonard Vincent, Professor, Fullerton College, writes:

"This guide is designed to serve my Biology of Insects and Spiders students as well as Orange County naturalists and residents. It is formatted as a ladder to direct the observer in the determination of the identity of spiders based on the habitat and web structure. These characteristics lead the observer to a page of thumbnail photos and then to a page of macro-photos of the particular spider."

This site has active spider identification and discussion forums, a growing list of species guides, spider FAQs, information about spider identification (and various other articles to come in the future), etc. Mostly directed more towards the casual observer and people new to spiders, however the writers there (self included) know the subject well and can help those seeking more in-depth help.

Very nice, accurate website by arachnologist Robb Bennett. Includes a 2010 species checklist for British Columbia and many other goodies (such as a decent-sized photo gallery and collection maps, etc).

An annotated list of the species of spiders (Arachnida: Araneae) found in South Dakota, compiled from records in the author's collection (KMP), the Denver Museum of Nature and Science (ZA), and published journal articles. Valid reports of additional species are welcome.
